There is DEFINITELY a difference between the two. Intuition isn't necessarily nerve wrecking. I'm one of the most inttuitive people you'll ever come across. I hear it ALL the time and at LEAST 9 times out of 10, my instincts are right on. Occasionally, I'm not, but usually even then, my instincts were partially correct.
You may not think this has anything to do with it, but I'm a very spiritual person. I read the Bible daily and pray ALL THE TIME. I ask God to give me wisdom and discernment, guidance and direction. I've done this for years. As a result, my intuition amazes me sometimes.
Even in my business...I'm a certified posture alignment and pain management specialist. If someone has an issue with gait, shoulder pain, etc. I seem to be able to figure out what muscle(s) are working, not working, what's taking over and MANY times, WHERE the problem started. i.e. if you tell me you have shoulder pain, I figure out that it started in your hips. This happened FIVE times, just last night. May not make sense to you, but ask my clients. I figure it out and fix it. It's MORE than training and study.......FAR more.
I was thinking about a girlfriend this morning I haven't talked to in several months. As I was leaving the bank, her husband pulled up beside me and was on the phone with her. He handed the phone to me to talk to her. That kind of thing happens all the time, too. If I think about someone I haven't seen or talked to in a long time, ususally within 2-3 days, if not the same day, I'll see them, get a call, etc.
I think having a remarkable intuition is one of God's greatest gifts. Along with that comes a great deal of wisdom that He gives, too. I LOVE IT!
